Legal Steer Axle Weight in Michigan

Lawyers who deal with truck accidents where weight regulations are an issue should contact the Michigan Department of Transportation to see what certificates were filed with the state prior to the accident. Without a permit, Michigan tractor weight limits cannot exceed 80,000 lbs. A five-axle station wagon can support a gross weight of 12,000 lbs on the steered axle, driven axles supporting 34,000 lbs and trailer axles 34,000 lbs gross weight. The gross weight of bridges formula was developed to avoid loads on highway bridges caused by heavy trucks. The formula provides a standard for controlling the distance between truck axles and the weight on those axles. Vehicles with a gross weight of 80,000 pounds or less may be eligible for increased weights with the bridge`s gross weight formula. Vehicles with a gross weight greater than 80,000 pounds or a gross weight calculated using the bridge weight formula are not eligible for bridge weights. W = The maximum weight, in pounds, that may be carried on a group of two or more axles up to the next 500 pounds; L = distance in feet between the outer axles of two or more consecutive axles; N = The number of axes considered. The problem with exceeding weight limits is that it can affect steering and braking, which can lead to catastrophic truck accidents. An overloaded truck also takes longer to stop.

In addition, the truck slows down during upgrades and faster during decommissioning. If the brakes are forced to work too hard, they can let go. * For each combination of legal vehicles, there is only 1 tandem axle with a total weight of 16,000 lbs. per axle and no other combination of tandem axles in such a vehicle combination should exceed a gross weight of 13,000 lbs per axle. For a combination of tractor and semi-trailer with not more than 5 axles, load, 2 sets of tandem axles with a total weight of 16,000 lbs per axle are permitted if no other axle is within 9 feet of an axle of the combination. Michigan has adopted FBF nationwide, but also allows the state`s old limits for trucks weighing more than £80,000 gross. These stock limits have lower weight limits for single axles and tandem axles: a typical straight dump truck would be limited to 18 km on the front axle, 32 km on the tandem drive axles, and then 13 km on each auxiliary axle. Theoretically, a quint with 3 auxiliary axles could weigh up to 89,000 lbs. In reality, however, it is not possible for a typical straight dump truck like a Quint to distribute enough weight across the front axles to make this possible (tandem drive axles would inevitably exceed the 32k limit, while the steered axle and front thrust axle would be underloaded), and therefore a typical Quint could not weigh more than 64,000 lbs due to these axle limitations and distribution.

weight. That`s why station wagons (puppy trailers and transfer trailers) are so popular in Michigan. Michigan Truck Operator Map (with vehicle weight restrictions)Note: The weight restrictions shown here do not reflect seasonal restrictions. The link above shows the distribution of vehicle weight limits in IM with seasonal restrictions, as well as designated roads (green and gold roads) where vehicles are 102″ wide (96″ wide on non-designated roads). In Michigan, a combined platform (puppy or transfer trailer) offers the highest total weight and payload per trip – 40+ tons of payloads are possible with wetsuits (or “trains” as they are commonly called in MI). However, a 7-axle Super Dump can carry 32 tons on a single straight truck, which is actually more productive for short and medium haul jobs. A unique feature of the Super Dump is the way the Strong Arm trailed axle distributes significant weight from the tandem drive axles to the front axle(s). With this weight redistribution capability and 13,000 to 14,000 lbs on the rear axle, a 7-axle Super Dump (legal and practical) can weigh up to 95,000 lbs in Michigan – which would mean payloads of 32 tons.

If you factor in processing time — all the extra time spent in transit and in landfills with puppies and transfers — super dumps will typically be able to make 50% more trips in a workday. So if a puppy/transfer/train can make 4 trips at 44 tons per trip, he would pull 176 tons that day. While a Super Dump would make 6 trips at 32 tons per trip, that would be 192 tons that day. As part of a tandem axle assembly *only on designated lines The bridge formula allows up to 20,000 lbs per single axle if the vehicle is equipped with sufficiently large tires. The weights of the steered axle vary depending on the total weight of the vehicle. The weight of the load must be properly balanced so that an axle or set of axles is not overloaded. Truck accidents due to excessive loads are, by their very nature, usually more serious injuries or deaths. The Federal Motor Carrier Safety Administration regulates and regulates laws regarding Michigan truck weight limits for commercial vehicles. They concern commercial gross weight, combined weight, axle weight and tyre load. In Michigan, no more than 700 pounds per inch of tire width is allowed for a single axle. Since truck accidents often cause serious injury due to the physics of shear, they are often the subject of litigation.

These cases can be very difficult for lawyers to prove. For this reason, Michigan truck accident lawyers must take strong action during the judicial investigation to obtain evidence that the truck`s weight limits in Michigan were violated by the excessive weight of the truck or that the load was distributed negligently. Depending on the conditions listed, your vehicle may be subject to the maximum values of the bridge formula or normal loading standards. The maximum wheel load must not exceed (pounds per inch tire width) The bridge formula applies to vehicles travelling on roads and specially designated roads that: Normal overtaking when seasonal load restrictions are not in place Source of information: www.truckingsafety.org/Portals/0/GuideBooks/18th%20Ed%20TDGB.pdf vehicles 80,000 lbs (or less) Gross weight according to the Bridge formula.
